Currently, Vector's orbit on Horizons is the orbit planned by mission scientists. The satellite is not immune to a voluntary or accidental change of orbit by the encounter with another gravitational object.Horizons should be regularly monitored to update the .xyzv file if necessary.

What will become of the satellite when approaching so close to the Sun, will it resist?It will be interesting to follow this mission.

On Aug. 17, the OSIRIS-REx spacecraft obtained the first images of its target asteroid Bennu from a distance of 1.4 million miles (2.2 million km), or almost six times the distance between the Earth and Moon. This cropped set of five images was obtained by the PolyCam camera over the course of an hour for calibration purposes and in order to assist the mission’s navigation team with optical navigation efforts. Bennu is visible as a moving object against the stars in the constellation Serpens.Credits: NASA/Goddard/University of Arizona
